We look at the division of 143637 by 86 
We want to figure out the number of times 143637 can be divided by 86.

Going ahead to step 1:
86 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 86

Step 2:
86 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 86

Advancing to step 3:
86 can be fit into 143 1 times, resulting in a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 86 away from 143, we end up with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 86

Moving on to step 4:
576 divided by 86 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 516 from 576 to get 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 86

Advancing to step 5:
If we divide 603 by 86, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Subtracting 602 from 603 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 86

Let's proceed to step 6:
The number 86 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 1670.0
If we take 0 away from 17, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
86 can be fit into 170 1 times, resulting in a remainder of 84.
The next digit of our result is 1. 
Result so far: 1670.1
If we take 86 away from 170, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
When dividing 840 by 86, we get 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 1670.19
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1670.197
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
86 goes into 580 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1670.1976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1670.19767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
380 divided by 86 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 1670.197674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1670.1976744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1670.1976744 with a remaining 1.6e-07.
